Android Question Compress data with Zlib

[Blue.Sky]

Hi
I apply zlip function data in php (for compress) and uncompress in b4a
Example i compress "Hello Erel"
result is "eJzzSM3JyVdwLUrNAQATlQOd"
so result is longer than source,however i want to compress data
Please explain zlip usage to me

compression works best on MUUUUUCH longer data, with repeated patterns within them. Try compressing a string made up of 1000 "a"'s.

for 100 character not possible?

In such a case, it is better to not compress the data. The compressed result may be bigger because of the extra data, e.g. the dictionary. Usually, a compression is only interesting with uncompressed data (so compressing a JPG file is mostly a waste of time) and enough data to have repetitive patterns.

Try compressing all the files into a single compressed unit instead of compressing the individual items separately.
